The "'K' type All Steel with no separate trussing" cars were built in 1928 (15 First class, and 14 Third class) and 1931 (4 Third class). Whereas previous Pullman cars built had been a combination of wood and steel, these cars were all steel but were still built to the traditional design. The cars served on the Southern, the London and North Eastern, and the Great Western railways, and most of the cars eventually ended up on the Southern region of British Railways. Five types of coaches are available:
